Works with remote but not panel controls
After about two hours of operation, the picture shuts off leaving the screen black, but the sound continues. It seems to be temperature related. It happens more often when the room temperature is warm or hot.
I haven't taken any steps yet to fix it. I'm just researching the problem right now. I'll probably have to take it in to be fixed.

Re: black screen, sound ok
Open it up and see if it is full of dust at all. Also take a look and see if anything smells burnt at all. If you don't feel comfortable doing this, then like you said, you should take it to be fixed but first see if it is a dust or blocked airflow problem. It sounds like a power supply/overheating problem in the circuitry though.
good luck and let me know of any further questions you may have and I would be glad to help answer them

First of all, change the input device to something you know works for sure. Look for any jammed buttons on remote or on control panel. (This can happen, if you inadvertently sit on the remote hidden under a magazine or newspaper) Check the picture settings to ensure that these are ok. If problem persists, it might need attention by a qualified service technician.
Hi it sounds like it has had an elctric fault like a resistor failing. The click you heard would be a internal switch that cuts off the elctric supply to the screen to stop furthe damage hapening. It could even be something simple like a bad solder and in that case will need locating and resoldering. How old is the telly and how often is it used. When you switch it off leave it off for about an hour then try again if you have allready done this then it probably is a blown resistor are you sure nothing has been pressed on controll have you tried seeing if you can acess the menu screen via the remote and see if that comes up on the screen let me know ok
Check with Samsung, this model should still be under the 3 year warranty. You are having a problem with the backlight power supply. You can look on the back of the unit for the manuf. date, if its less than 3 years then go to www.samsung.com and process the online service request form.

most trouble like that shows a protect mode, there's a problem with the system and it shuts down,if the sound remain after the screen off, the back lights circuit is only in trouble.whole system shutdown.tell me
> IF IT WASNT DIGITAL HD I WOULD HAVE SUSPECTED HIGH VOLTAGE POWER SUPPLY BUT THAT DOES NOT EXIST HERE. Well, not completely true; the fluorescent backlight is still a high voltage device, even if only hundreds of volts instead of kilovolts, and either the lamp(s) or the power supply for it (them) is causing the dropout of your picture.When it does it next time, look at the screen from various angles, I think you will see that video content is still there.
